Publish your Community infrastructure levy data
Follow this guidance when providing your Community infrastructure levy data.
There are currently no obligations on any party to provide data in conformance to this specification. A future version of this specification may be published on GOV.UK, and cited as one of a number of official data standards for the provision of planning data under the Levelling-up and Regeneration Act 2023, other regulations, contracts, and agreements.
Providing planning data means making it available publicly to a standard, so that anyone using services such as planning.data.gov.uk can:
- find it
- understand its quality, meaning and purpose
- trust it will be accurate and maintained
Providing your Community infrastructure levy data
Take the following steps to provide your Community infrastructure levy data:
- Prepare your data
- Check your data
- Publish your data
- Tell us about your data
- Keep your data up to date
Prepare your data
Start by reviewing any data we may already have about your organisation on planning.data.gov.uk using the check and provide service. This might include:
- any data you have provided in the past
- information found on your website
- open data from other public sources
We treat the data you provide as being more authoritative than data we previously collected or that we find elsewhere.
You can download tabular data we have for your organisation as a CSV file from the check and provide service, then edit it using a spreadsheet or other CSV editors.
You must provide data for the mandatory fields identified.
Datasets
For Community infrastructure levy you may provide the following dataset:
You need to provide the dataset in a CSV file and follow the government tabular data standard.
Field names
You can use a field name with uppercase, lowercase and any punctuation characters.
For example, you can use any of the following names for the start-date field in your data
StartDateStart DateSTART_DATEstart.date
Reference values
Each dataset has a reference field.
Reference values are important to help people find and link to your data.
If you do not have a reference value for an item, you will need to create one that:
- is unique within your data
- does not change when the data is updated
A good reference is something you already use. If your reference is not unique, you can make them unique by adding the year or full date. Great references are:
- short
- easy to read
- easy to pronounce and remember
Date values
All dates must be in the format YYYY-MM-DD as set out in the guidance for formatting dates and times in data.
Where you don't know the precise date you can enter just the month YYYY-MM or even just the year YYYY.
The platform will default a start-date to the first of the month, or the first of January, and an end-date to the last day of the month, or the last day of December. For example:
2025-04-192025-042025

Check your data
Use the check and provide service to review your data before you publish it. The service will show you how the data will appear on planning.data.gov.uk along with feedback on how you might improve your data.
Publish your data
Publishing your data consists of two parts:
- An endpoint where the data can be downloaded from
- A source webpage where the information contained in the data is presented on your website
Endpoint
Make your data available at a public endpoint. An endpoint is a URL from which anyone can download the data. This can be either:
- a single file hosted on your website
- a file hosted on another public website including GitHub
Ensure your endpoint URL is documented and linked to from a public webpage to help people easily find and download the data.
The documentation webpage for your endpoint should include a clear statement that the data is provided as open data under the Open Government Licence.
Source webpage
The source webpage is where a user can see the same information that is shown in the data.
This is usually one of your existing planning policy pages on your official .gov.uk website.
It is important that the source webpage links to the endpoint documentation webpage to help users trust the authenticity of the data.
Tell us about your data
Once you have published the data, use the check and provide service to tell us where it is. This is so we can index the data and quickly make it available nationally on planning.data.gov.uk.
For each dataset, you will need to provide the:
- source webpage URL where the information in the data is presented on your website
- endpoint URL where you can collect the data
The service also asks for your name and email address as a point of contact in case of any issues.
Keep your data up to date
Continue to improve your data and act on the the service feedback to make sure that your data meets the specification.
We update planning.data.gov.uk with any changes to the data at all the endpoint URLs each day.
Publish your changes to the same endpoint URL. If you create a new endpoint you need to tell us about your data again.
